Not to be confused with "anti-relativism," a philosophical position opposed to cultural relativism.

Anti-relativity refers to the denial of Albert Einstein's Theory of Relativity. While relativity denial is mostly the province of lone cranks these days, it was much more widespread in Einstein's day, often being collectively referred to as "the anti-relativity movement."

In 1931 the book, Hundert Autoren Gegen Einstein (A Hundred Authors Against Einstein),[1] was published. The book only included one physicist, and can be seen now as "a dying cry from the old guard of science" based primarily on philosophical objections.[2]

In what might be more appropriately called "Einstein denial," some anti-Semites did not claim that Einstein was wrong, but that he had plagiarized or otherwise ripped off earlier ideas from (insert your favored ethnic group here).[3]

Some Objectivists question or deny relativity as it doesn't fit neatly into Ayn Rand's metaphysical notions about causation (and is probably corrupted by dirty Kantian philosophy to boot).[4] The most notable Objectivist anti-relativist was Petr Beckmann, who attempted to replace it with a theory conjecture called "Galilean Electrodynamics."
